Matt Posted May 11 Report Share Posted May 11 (edited) Hey guys I’m having an issue with my 1928 WH serial #634A that I was hoping someone may be familiar with. I have had a couple of instances where the bolt would only slide about 1/4 of the way forward and then lock up. The only way to get it free was to remove the full auto pin, safety pin and pin that holds the trigger on in order to free up the sear from the bolt so I could separate the lower from the upper. I couldn’t see any visible damage and other than the parts in the trigger being dirty it all seemed to go back together fine and functions properly. Has anyone else had this issue?

TD. Posted May 11 Report Share Posted May 11 On a previous post you said the buffer pilot did not have a USGI manufacturer's mark and was probably a West Hurley product. Did you change that out before firing? Depending on the type of West Hurley buffer pilot you have, sometimes the flange will be loose on the shaft and cause issues. I am also curious if the actuator has a manufacturer's mark. Since you have taken the frame apart, check each part for a manufacture's part. I have heard the West Hurley Safety Levers will sometimes more around in the Sear and Sear levers and cause issues. If you're having functioning problems, these out of spec parts are the first thing to change out. Link to comment Share on other sites More sharing options...
Matt Posted May 11 Author Report Share Posted May 11 Ok thanks for the input. Yes I changed out the buffer pilot but I will have to check the other parts for a manufacture mark. Link to comment Share on other sites More sharing options...
Dpedersen Posted May 11 Report Share Posted May 11 Make sure the semi/full auto rocker is facing to the rear as shown in the pic. If not, it will cause the bolt to lock up. Link to comment Share on other sites More sharing options...

deerslayer Posted May 12 Report Share Posted May 12 West hurley frequently have deep bolt pockets which means if you put the gun in semi auto, the rocker rises up and the bolt can travel over it which can then cause what you describe. Confirm if this is happening when you have the gun in semi Link to comment Share on other sites More sharing options...

Confirm if this is happening when you have the gun in semi Sorry I’m just seeing this but I will definitely check that out. I feel like this must be the issue because the last time I took it out to shoot it it was locked up like this and the only time I mess with the firing selector is when I have cleaned it. thanks for the input. How would I go about fixing this issue? Link to comment Share on other sites More sharing options...
deerslayer Posted May 22 Report Share Posted May 22 Don't ever put it in semi! One solution has been to add material to the top of the actuator. Link to comment Share on other sites More sharing options...
TD. Posted May 22 Report Share Posted May 22 deerslayer, If someone were to manufacture an oversize actuator, would it be fairly easy for someone like you, or PK., or reconbob, or Got Uzi to fit the oversize actuator to the West Hurley receiver to achieve the proper clearance?

deerslayer Posted May 22 Report Share Posted May 22 I havent done it, but a little welding on the top of a waffenmeister actuator might be just the thing. Link to comment Share on other sites More sharing options...
StrangeRanger Posted May 22 Report Share Posted May 22 You'd have to widen the slots in the knob base to match Link to comment Share on other sites More sharing options...
deerslayer Posted May 22 Report Share Posted May 22 No. Just on the flat part. Did that to make a post sample work a little better when it got milled too deep Link to comment Share on other sites More sharing options...
